CONSTITUTION:A round tube 10 of high heat conductivity such as Cu, Al etc. is bent successively at an angle of 180 deg. and a refrigerant body in which adjoining straight parts 50 with bent parts 40 between are parallel to each other is formed in body. Separately manufactured fins 20 provided with two side fin parts 22 and central fitting parts 21 having the same inner diameter with outer diameter of the refrigerant tube and side opening of less than 180 deg. are formed in one body by insertion to manufacture a heat collecting and radiating panel.

能性が大であるという欠点があった。Conventionally, a heat collecting and dissipating panel for this purpose has a configuration as shown in FIG.
A plurality of finned tubes are arranged in parallel, and the refrigerant passages of adjacent finned tubes are connected by welding a round bend pipe 4 at the welding part 3 (argon welding in the case of aluminum material), and a round refrigerant pipe 1 is connected to this by welding (argon welding in the case of aluminum material). were similarly welded and formed. However, this method of manufacturing a heat collecting and dissipating panel has disadvantages in that the cost of welding the vent portion and the refrigerant pipe is high, and there is a high possibility of refrigerant leaking at the welded portion.

することを特徴とする、集放熱パネルの製作法にある。That is, the present invention is a method for manufacturing a heat collecting and dissipating panel used in a heat pump type heating and cooling device that utilizes solar heat and air heat. The straight part of the refrigerant pipe has an inner diameter substantially equal to the outer diameter of the refrigerant pipe.
A method of manufacturing a heat collecting and dissipating panel is characterized in that fins having a central fitting part having a side opening with an angle of less than 0.0 degrees and a fin part at the center are joined together.

以下本発明を第２図に例示したその好適な実施例につい

ることは言をまたない。As shown in FIG. 2, according to the present invention, first, a single round tube 10 of a metal with good thermal conductivity such as copper or aluminum is folded one after another and bent by 180 degrees to form a bent portion 40.
Refrigerant pipes are integrally formed in parallel with adjacent straight portions 50 via the refrigerant pipes. Although FIG. 2 only shows a part of such one straight section 50 and one vent section 40 following it, it is needless to say that the overall structure is as shown in FIG. 1. Not again.

開口を形成するように設定するのである。A separately manufactured fin 20 is attached to the straight portion 50 of the refrigerant pipe thus formed. That is, the fin 20 has fin portions 22 on both wings and a fitting portion 21 in the center. The central fitting portion 21 has a tubular shape with an inner diameter that substantially matches the outer diameter of the refrigerant tube 10 and a side opening 23 with an angle of less than 180 degrees. Therefore, bring this fin 2o so that the side opening 23 of the central fitting part 21 is aligned with the refrigerant pipe lO, and forcefully push it toward the refrigerant pipe to fit them together (this is called a recess). Therefore, the opening angle of the side opening is such that the center fitting part 21 bends to the maximum diameter of the refrigerant pipe 1o with sufficient restoring force during this pushing operation, and is fitted into the refrigerant pipe 1o. The setting is such that an opening is formed so that surface-to-surface contact can be achieved firmly by force.
